Tyrosine kinase inhibitors (TKIs) have improved chronic myeloid leukemia (CML) management, but advanced CML phases still have poor prognoses. New research is crucial to enhance treatment strategies and improve survival for patients with accelerated or blast phase CML.
Area of Science:
- Hematology
- Oncology
- Pharmacology
Background:
- Tyrosine kinase inhibitors (TKIs) have revolutionized chronic myeloid leukemia (CML) treatment.
- TKI therapy significantly reduced the annual progression rate to advanced CML phases from over 20% to 1-1.5%.
Purpose of the Study:
- To highlight the challenges in managing advanced phase CML (accelerated or blast phase).
- To emphasize the need for novel therapeutic strategies due to the dismal prognosis and limited long-term survival in advanced CML.
Main Methods:
- Review of current treatment paradigms for advanced phase CML.
- Analysis of survival data and treatment outcomes in the context of TKI therapy and allogeneic hematopoietic cell transplantation.
Main Results:
- Despite TKI advancements, no consensus exists for optimal therapy in advanced CML.
- Conventional strategies offer limited long-term survival, with median survival ranging from 7 to 11 months.
Conclusions:
- Advanced phase CML remains a critical area requiring further research.
- Developing innovative treatments is essential to improve outcomes for CML patients in advanced stages.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
